CROSS REFERENCE TO RELATED APPLICATION

This application claims priority of U.S. Provisional Appl. No. 62/578,899, filed Oct. 30, 2017, which is hereby incorporated by reference in its entirety.

BACKGROUND

Aldehyde dehydrogenases (ALDH) constitute a family of enzymes that play a critical role in oxidizing various cytotoxic xenogenic and biogenic aldehydes. There are at least 19 members/isozymes of the ALDH family, where the various isozymes may exhibit different substrate specificity and/or cellular location relative to other members of the family

Increased expression of various ALDH isozymes have been reported in various human cancers and are associated with cancer relapse. Family member ALDH1A1 is a cancer stem cell marker, and its expression correlates with poor prognosis in a number of malignancies. In addition, ALDH1A1 appears to be an important factor in tumor aggressiveness. In addition, tumors and cancer stem cells resistant to chemotherapy and radiation are associated with high expression of ALDH1A1. Although the majority of the research community has considered ALDH1A1 as a marker of cancer stem cells and a predictor of the prognosis, this enzyme plays an important role in the biology of tumors and cancer stem cells. Initial evidence using non-specific ALDH inhibitors and siRNA confirms the involvement of ALDH1A1 in the first line of targets for targeted drug development in order to enhance the efficacy of chemotherapy and radiation.

ALDH1A1 has also been shown to play a role metabolism and obesity. ALDH1A1 is expressed predominantly in white adipose tissues in mice and humans. White adipose tissue selective ALDH1A1 knockdown in obese mice limited weight gain and improved glucose homeostasis. ALDH1A1 inhibitors are therefore desirable as anti-obesity agents.

Therefore, this disclosure provides compounds and compositions that inhibit aldehyde dehydrogenases, such as aldehyde dehydrogenase 1A1, for use for the treatment of various conditions, such as cancer, inflammation, or obesity

DETAILED DESCRIPTION Terminology

In order for the present disclosure to be more readily understood, certain terms and phrases are defined below and throughout the specification.

The articles “a” and “an” are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element.

The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited.

In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” or the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03. The open-end phrases such as “comprising” include and encompass the close-ended phrases. Comprising may be amended to the more limiting phrases “consisting essentially of” of “consisting of” as needed.

The definition of each expression, e.g., alkyl, m, n, or the like, when it occurs more than once in any structure, is intended to be independent of its definition elsewhere in the same structure.

It will be understood that “substitution” or “substituted with” includes the implicit proviso that such substitution is in accordance with permitted valence of the substituted atom and the substituent, and that the substitution results in a stable compound, e.g., a compound which does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, or other reaction.

The term “substituted” is also contemplated to include all permissible substituents of organic compounds. In a broad aspect, the permissible substituents include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, aromatic and nonaromatic substituents of organic compounds. Illustrative substituents include, for example, those described herein below. The permissible substituents may be one or more and the same or different for appropriate organic compounds. For purposes of this disclosure, the heteroatoms such as nitrogen may have hydrogen substituents and/or any permissible substituents of organic compounds described herein which satisfy the valences of the heteroatoms. This disclosure is not intended to be limited in any manner by the permissible substituents of organic compounds. “H—” is not considered a substituent.

Suitable groups that may be present on a “substituted” or “optionally substituted” position include, but are not limited to, e.g., halogen; cyano; —OH; oxo;—NH₂; nitro; azido; alkanoyl (such as a C₂-C₆ alkanoyl group); C(O)NH₂; alkyl groups (including cycloalkyl and (cycloalkyl)alkyl groups) having 1 to about 8 carbon atoms, or 1 to about 6 carbon atoms; alkenyl and alkynyl groups including groups having one or more unsaturated linkages and from 2 to about 8, or 2 to about 6 carbon atoms; alkoxy groups having one or more oxygen linkages and from 1 to about 8, or from 1 to about 6 carbon atoms; aryloxy such as phenoxy; alkylthio groups including those having one or more thioether linkages and from 1 to about 8 carbon atoms, or from 1 to about 6 carbon atoms; alkylsulfinyl groups including those having one or more sulfinyl linkages and from 1 to about 8 carbon atoms, or from 1 to about 6 carbon atoms; alkylsulfonyl groups including those having one or more sulfonyl linkages and from 1 to about 8 carbon atoms, or from 1 to about 6 carbon atoms; aminoalkyl groups including groups having one or more N atoms and from 1 to about 8, or from 1 to about 6 carbon atoms; mono- or dialkylamino groups including groups having alkyl groups from 1 to about 6 carbon atoms; mono- or dialkylcarboxamido groups (i.e. alkylNHC(O)—, (alkyl₁)(alkyl₂)NC(O)—, alkylC(O)NH—, or alkyl₁C(O)N(alkyl₂)—) having alkyl groups from about 1 to about 6 carbon atoms; carbocyclyl such as aryl having 6 or more carbons and one or more rings, (e.g., phenyl, biphenyl, naphthyl, or the like, each ring either substituted or unsubstituted aromatic); or a saturated, unsaturated, or aromatic heterocycle having 1 to 3 separate or fused rings with 3 to about 8 members per ring and one or more N, O or S atoms, e.g. coumarinyl, quinolinyl, isoquinolinyl, quinazolinyl, pyridyl, pyrazinyl, pyrimidinyl, furanyl, pyrrolyl, thienyl, thiazolyl, triazinyl, oxazolyl, isoxazolyl, imidazolyl, indolyl, benzofuranyl, benzothiazolyl, tetrahydrofuranyl, tetrahydropyranyl, piperidinyl, morpholinyl, piperazinyl, and pyrrolidinyl.

In certain embodiments “optionally substituted” includes halogen, hydroxyl, cyano, nitro, oxo, —CONH₂, amino, ono- or di-C₁-C₄alkylcarboxamide, and C₁-C₆hydrocarbyl , which C₁-C₆hydrocarbyl group, a hydrocarbon chain in which carbon atoms are joined by single, double or triple bonds, and any one carbon atom can be replaced by O, NH, or N(C₁-C₄alkyl) and which hydrocarbyl group is optionally substituted with one or more substituents independently chosen from hydroxyl, halogen, and amino When the substituent is oxo (═O) then 2 hydrogen atoms are replaced. When an oxo group substitutes an aryl or heteroaryl group, aromaticity of the group is lost. When an oxo group substitutes a heteroaryl group the resulting heterocyclic group can sometimes have tautomeric forms. For example a pyridyl group substituted by oxo at the 2- or 4-position can sometimes be written as a hydroxypyridine.

The term “saturated,” as used herein, pertains to compounds and/or groups which do not have any carbon-carbon double bonds or carbon-carbon triple bonds.

Dosage will depend upon the substance or substances administered, the therapeutic endpoint desired, the diagnostic endpoint desired, the desired effective concentration at the site of action or in a body fluid, and the type of administration. Information regarding appropriate doses of substances are known to persons of ordinary skill in the art and may be found in references such as L. S. Goodman and A. Gilman, eds, The Pharmacological Basis of Therapeutics, Macmillan Publishing, New York, and Katzung, Basic & Clinical Pharmacology, Appleton & Lang, Norwalk, Conn. (6.sup.th Ed. 1995). In some embodiments, the compounds and compositions of the present disclosure may be administered to a subject. Suitable subjects include a cell, population of cells, tissue or organism. In certain embodiments, the subject is a mammal such as a human. The compounds may be administered in vitro or in vivo.

The disclosure includes methods in which one or more compounds are an admixture or otherwise combined with one or more compounds and may be in the presence or absence of commonly used excipients (or “pharmaceutically acceptable carriers”); for example, but not limited to: i) diluents and carriers such as starch, mannitol, lactose, dextrose, sucrose, sorbitol, cellulose, or the like; ii) binders such as starch paste, gelatin, magnesium aluminum silicate, methylcellulose, alginates, gelatin, sodium carboxymethyl-cellulose, polyvinylpyrrolidone or the like; iii) lubricants such as stearic acid, talcum, silica, polyethylene glycol, polypropylene glycol or the like; iv) absorbents, colorants, sweeteners or the like; v) disintegrates, (e.g., calcium carbonate and sodium bicarbonate) such as effervescent mixtures or the like; vi) excipients (e.g. cyclodextrins or the like); vii) surface active agents (e.g., cetyl alcohol, glycerol monostearate), adsorptive carriers (e.g., kaolin and bentonite), emulsifiers or the like.

Furthermore, the disclosure includes compositions prepared using conventional mixing, granulating, or coating methods and may contain 0.01 to 90% of the active ingredients. In some embodiments, the one or more compounds are for pharmaceutical use or for diagnostic use. Such methods can be used, for example, to prepare a bio-enhanced pharmaceutical composition in which the solubility of the compound(s) is (are) enhanced. In some embodiments, the resulting compositions contain a pharmaceutically effective amount of a compound for pharmaceutical or diagnostic use. The resulting compositions (formulations) may be presented in unit dosage form and may be prepared by methods known in the art of pharmacy. All methodology includes the act of bringing the active ingredient(s) into association with the carrier which constitutes one or more ingredients. Therefore, compositions (formulations) are prepared by blending active ingredient(s) with a liquid carrier or a finely divided solid carrier, and/or both, and then, if needed, shaping the product into a desired formulation.

“Therapeutically effective amount” or “effective amount” refers to the amount of a compound that, when administered to a subject for treating or diagnosing or monitoring a disease, or at least one of the clinical symptoms of a disease or disorder, is sufficient to affect such treatment for the disease, disorder, or symptom. The “therapeutically effective amount” can vary depending on the compound, the disease, disorder, and/or symptoms of the disease or disorder, severity of the disease, disorder, and/or symptoms of the disease or disorder, the age of the subject to be treated, and/or the weight of the subject to be treated. An appropriate amount in any given instance can be readily apparent to those skilled in the art or capable of determination by routine experimentation.

“Treating” or “treatment” of any disease or disorder refers to arresting or ameliorating a disease, disorder, or at least one of the clinical symptoms of a disease or disorder, reducing the risk of acquiring a disease, disorder, or at least one of the clinical symptoms of a disease or disorder, reducing the development of a disease, disorder or at least one of the clinical symptoms of the disease or disorder, or reducing the risk of developing a disease or disorder or at least one of the clinical symptoms of a disease or disorder. “Treating” or “treatment” also refers to inhibiting the disease or disorder, either physically, (e.g., stabilization of a discernible symptom), physiologically, (e.g., stabilization of a physical parameter), or both, or inhibiting at least one physical parameter which may not be discernible to the subject. Further, “treating” or “treatment” refers to monitoring, delaying or preventing the onset or reoccurrence of the disease or disorder or at least symptoms thereof in a subject which may be exposed to or predisposed to or may have previously suffered from a disease or disorder even though that subject does not yet experience or display symptoms of the disease or disorder.

Pharmaceutical Compositions

While it is possible for compounds of the present disclosure to be administered as the raw chemical, it is also possible to present them as a pharmaceutical formulation. Accordingly, the present disclosure provides a pharmaceutical formulation comprising a compound or a pharmaceutically acceptable salt, prodrug or solvate thereof, together with one or more pharmaceutically acceptable carriers thereof and optionally one or more other therapeutic ingredients. The carrier(s) must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not deleterious to the recipient thereof. Proper formulation is dependent upon the route of administration chosen. Any of the well-known techniques, carriers, and excipients can be used as suitable and as understood in the art; e.g., in Remington's Pharmaceutical Sciences. The pharmaceutical compositions of the present disclosure can be manufactured in a manner that is itself known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or compression processes, for example.

The formulations include those suitable for oral, parenteral (including subcutaneous, intradermal, intramuscular, intravenous, intraarticular, and intramedullary), intraperitoneal, transmucosal, transdermal, rectal and topical (including dermal, buccal, sublingual and intraocular) administration although the most suitable route depends upon for example the condition and disorder of the recipient. The formulations can conveniently be presented in unit dosage form and can be prepared by any of the methods well known in the art. All methods include the step of bringing into association a compound of the present disclosure or a pharmaceutically acceptable salt, prodrug or solvate thereof (“active ingredient”) with the carrier which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the active ingredient with liquid carriers or finely divided solid carriers or both and then, if necessary, shaping the product into the desired formulation.

The compounds can be formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion. Formulations for injection can be presented in unit dosage form, e.g., in ampoules or in multi-dose containers, with an added preservative. The compositions can take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and can contain formulatory agents such as suspending, stabilizing and/or dispersing agents. The formulations can be presented in unit-dose or multi-dose containers, for example sealed ampoules and vials, and can be stored in powder form or in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example, saline or sterile pyrogen-free water, immediately prior to use. Extemporaneous injection solutions and suspensions can be prepared from sterile powders, granules and tablets of the kind previously described.

Formulations for parenteral administration include aqueous and non-aqueous (oily) sterile injection solutions of the active compounds which can contain antioxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which can include suspending agents and thickening agents. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions can contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension can also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions.

In addition to the formulations described previously, the compounds of the present disclosure can also be formulated as a depot preparation. Such long acting formulations can be administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds can be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.

Methods and Processes

In certain embodiments, the disclosure relates to a method of treating an ALDH1A1 disorder, comprising administering to a subject in need thereof a therapeutically effective amount of a compound described herein.

In certain embodiments, the disclosure relates to any of the methods described herein, wherein the ALDH1A1 disorder is selected from the group consisting of cancer, inflammation or a disease or disorder associated with inflammation, and obesity.

In certain embodiments, the disclosure relates to any of the methods described herein, wherein the ALDH1A1 disorder is selected from the group consisting of colon cancer, pancreatic cancer, nasopharyngeal carcinoma, thyroid cancer, prostate cancer, ovarian cancer, head and neck squamous cell carcinoma, lung cancer, hepatocellular carcinoma, leukemia, brain tumors, estrogen-dependent growth of uterine fibroids, and breast cancer.

The disclosure provides a method of treating an ALDH1A1 disorder by administering a compound of the disclosure to a patient having an ALDHA1 disorder where the disorder is acquired chemoresistance or lysosomal autophagy in cancer cells. Autophagy is a process in which cellular material, such as damaged organelles and misfolded proteins, is delivered to lysosomes for degradation. While autophagy can have tumor suppression activity at an early stage of tumor development, it can also be harnessed by the cells of established tumors for cytoprotection. In this case autophagy can be targeted by anticancer agent to promote apoptosis and decrease chemoresistance.

In certain embodiments, the disclosure relates to any of the methods described herein, wherein the ALDH1A1 disorder is selected from the group consisting of atherosclerosis, ischaemic heart disease, acne vulgaris, asthma, autoimmune diseases, autoinflammatory diseases, celiac disease, chronic prostatitis, glomerulonephritis, hypersensitivities, inflammatory bowel disease, pelvic inflammatory disease, reperfusion injury, rheumatoid arthritis, sarcoidosis, transplant rejection, vasculitis, and interstitial cystitis.

In certain embodiments, the disclosure relates to a method of preventing or treating cancer in a subject in need thereof comprising administering a therapeutically effective amount of any one of the compounds described herein. In certain embodiments, the methods are useful for treating a wide variety of cancers, including carcinomas, sarcomas, leukemias, and lymphomas. Thus, the subject can have a cancer such as a carcinoma, a sarcoma, a leukemia, or a lymphoma. In some embodiments, the individual has lung cancer resulting from prolonged exposure to cigarette smoke.

Carcinomas that can be treated using a subject method include, but are not limited to, esophageal carcinoma, hepatocellular carcinoma, basal cell carcinoma (a form of skin cancer), squamous cell carcinoma (various tissues), bladder carcinoma, including transitional cell carcinoma (a malignant neoplasm of the bladder), bronchogenic carcinoma, colon carcinoma, colorectal carcinoma, gastric carcinoma, lung carcinoma, including small cell carcinoma and non-small cell carcinoma of the lung, adrenocortical carcinoma, thyroid carcinoma, pancreatic carcinoma, breast carcinoma, ovarian carcinoma, prostate carcinoma, adenocarcinoma, sweat gland carcinoma, sebaceous gland carcinoma, papillary carcinoma, papillary adenocarcinoma, cystadenocarcinoma, medullary carcinoma, renal cell carcinoma, ductal carcinoma in situ or bile duct carcinoma, choriocarcinoma, seminoma, embryonal carcinoma, Wilm's tumor, cervical carcinoma, uterine carcinoma, testicular carcinoma, osteogenic carcinoma, epithelieal carcinoma, and nasopharyngeal carcinoma, etc.

Specifically, the disclosure relates to the treatment, detection, or prognosis associated with a patient suffering from a head and neck squamous cell carcinoma (HNSCC), which are the most frequent malignancies of the upper aerodigestive tract. ALDH1-positive HNSCC patients have worse prognosis, which was associated with common clinicopathological features and poor prognostic factors. When isolated from HNSCC patients, ALDH1-positive cells (HNSCC-ALDH1+ cells) display radioresistance and represent a reservoir for generating tumors.

ALDH1A1 is also hypothesized to be a marker for normal and malignant human colonic stem cells (CSCs). In addition, ALDH1A1 may be used to track CSC overpopulation during colon tumorigenesis. Moreover, higher numbers of ALDH1A1-expressing cells in an adenoma is associated with a higher risk for metachronous adenoma, independent of adenoma size or histopathology. However, cytoplasmic and stromal expression of ALDH1A1 is not significantly associated with prognosis either in colon cancer or in rectal cancer. Furthermore, cytoplasmic expression of ALDH1A1 does not predict therapeutic vulnerability to palliative chemotherapy in patients with metastatic diseases. Interestingly, nuclear expression of ALDH1A1 is observed in a small subgroup of patients with colon and rectal cancer. In patients with colon cancer, nuclear expression is significantly associated with shortened overall survival. Besides nuclear localization, ALDH1A1 is present in the secretome of metastatic colon cancer cells. While not wishing to be bound by any particular theory, it is possible that extracellular ALDH1A1 protects the CSC against the hostile environment in the extracellular space, e.g. chemotherapeutic agents or oxidative conditions.

In addition, non-small cell lung cancers (NSCLC) express very high levels of ALDH1A1 in comparison with SCLC; the elevated expression of ALDH1A1 may be associated with malignant transformation to adenocarcinoma.

In papillary thyroid carcinoma (PTC), ALDH1A1 does not appear to be a marker for CSC, but it expression occurs in high levels in PTC. High ALDH1A1 expression in PTC is associated with a reduced lymph node recurrence-free survival (LN-RFS) and distant recurrence-free survival (DRFS) in PTC patients, relative to patients having low ALDH1A1 expression. Multivariate analysis confirmed that ALDH1A1 expression was an independent prognostic factor for LN-RFS and DRFS in PTC patients.

In addition, ALDH1A1 is up-regulated in clonal sub-populations of pancreatic cancer cell line, MiaPaCa-2. ALDH1A1 expression is highest in more highly-invading pancreatic cancer cells lines and data suggest that ALDH1A1 may be promote pancreatic cancer metastasis. Analysis of human tissue sections revealed ALDH1A1 to be abundantly expressed in the pancreatic cancer tissue. Moreover, high expression of ALDH1A1 in these cancers is found to be significantly associated with proliferation of the tumor cells. Cell populations with high ALDH activity are much more efficient at promoting tumor-initiation and have enhanced tumorigenic potential than cells that are high in CD133 expression (CD133(+)) and with low ALDH activity. Although CD133(+) cells may alone possess tumorigenic potential, they are significantly less tumorigenic than cells with high ALDH expression. In addition, high levels of ALDH1A1 expression contribute to the intrinsic and acquired resistance of in human pancreatic adenocarcinoma (MiaPaCa-2) cells to gemcitabine. Knock-down of ALDH1A1 expression with siRNA along with gemcitabine treatment results in a significant decrease in cell viability and an increase in apoptotic cell death in the gemcitabine-resistant MiaPaCa-2 (MiaPaCa-2/GR) cells. Additional studies showed that a combination treatment (dasatinib and gemcitabine) results in inhibition of cell proliferation and decreased survival of MiaPaCa-2/P (parental) and MIA PaCa-2/GR by reducing ALDH1A1 expression in ALDH1A1-enriched pancreatic cancer MiaPaCa-2 cells. In addition, using adoptive therapy with ALDH1A1-specific CD8(+) T cells eliminated ALDH enzymatically-active (or ALDH bright) cells, inhibited pancreatic tumor growth and metastases, or prolonged survival of xenograft-bearing immunodeficient mice. While not wishing to be bound by any particular theory, the available data strongly support the potential of ALDH1A1-based immunotherapy to selectively target CSCs in human cancer.

The association between ALDH1A1 expression and clinicopathological/prognostic parameters in breast cancer patients has also been evaluated. Through overall and subcategory analyses using data from15 publications that included 921 ALDH1A1-positive cases and 2353 controls, ALDH1A1 was proposed to be a biomarker that predicts tumor progression and poor survival of breast cancer patients.ALDH1A1 has also been suggested as being predictive for the prognosis of triple-negative breast cancer (TNBC), a subtype of breast cancer characterized by poor outcomes. In addition, the ALDH1A1 phenotype is an independent predictor of early tumor relapse (i.e., incidence of early local recurrence and distant metastasis) of invasive ductal carcinoma. ALDH1A1 expression has been shown to be associated with severity of breast cancer. More specifically, tumors associated with advanced stage, were node-positive, or of larger size are found to have higher ALDH1A1 expression in the tumor tissue. ALDH1A1 expression is also correlated with worse disease-free survival and overall survival in patients who had been treated with neoadjuvant chemotherapy. BRCA1-related breast cancers show more frequent epithelial and stromal (peritumoral) ALDH1A1 expression leading to the suggestion that ALDH1A1 may be a diagnostic marker and a therapeutic target of BRCA1-related breast cancer. Using ellipticine, an inhibitor of ALDH1A1 as a model, molecular simulation and docking studies revealed that amino acids present in the active site of human ALDH1A1, viz. Asn-117, Asn-121, Glu-249, Cys-302 and Gln-350, interact with ellipticine. At high concentrations (3 mM), ellipticine decreased the expression of ALDH1A1-positive breast cancer stem cells (BCSCs) in the SUM159 cell line. Ellipticine also reduced the formation of mammospheresby MCF7 and SUM159 breast cancer cell lines. Interestingly, when treated with a combination of ellipticine and paclitaxel, the percentage of ALDH1A1-positive BCSCs was decreased significantly in vitro.

Ovarian CSCs may be identified by their expression of ALDH1A1. High ALDH1 expression is significantly associated with poor clinical outcomes in serous ovarian cancer patients (P=0.0036). More recent data indicate that there is a link between ALDH1 and EGFR expression in high-grade serous ovarian carcinoma (HGSC) Immunopositivity for both ALDH1 and EGFR identifies a subgroup of highly aggressive, poor-prognosis cancers. In addition, ALDH enzymatically-active (or ALDH bright) tumor cells exhibit CSC properties and are resistant to chemotherapy. Finally, inhibition of ALDH1A1 results in disruption of ovarian cancer cell spheroid formation and cell viability.

ALDH1A1 is also a marker for malignant prostate stem cells and predictor of prostate cancer (PCa) patient outcome. ALDH1A1-expressing PCa cells exhibit high clonogenic and tumorigenic capacities. In addition, xenograft experiments showed that PCa in mice resemble histopathologic characteristics and heterogeneity of the parental PCa cells in humans. While ALDH1A1-expressing cells are sparse in normal human prostate tissues and limited to the basal component in normal prostates, in tumor specimens, increased ALDH1A1 expression is found not only in secretory type cancer epithelial cells but also in neuroendocrine tumor populations. Finally, high ALDH1A1 expression in PCa correlates positively with Gleason score (P=0.01) and pathologic stage (P=0.01), and is inversely associated with overall survival and cancer-specific survival of PCa patients (P=0.00093 and 0.00017, respectively). ALDH1A1 is also a valuable biomarker for prognosis. The crucial role of ALDH1A1 enzymatic activity in CSC maintenance was demonstrated by DEAB (an ALDH inhibitor) induced repression of sphere formation by RWPE-2, CWR-R1 and DU-145 PCa cell lines.

In addition, ALDH1A1 has been recently suggested to be a novel CSC marker and a valuable predictor of poor survival and enhanced invasiveness and metastatic ability in nasopharyngeal carcinoma (NPC). Furthermore, ALDH1A1 expression in the invasive front (which underlies the biological aggressiveness and epithelial-mesenchymal transition (EMT) in human malignances) links closely with EMT characteristics and tumor aggressiveness, confirming the prognostic value of ALDH1A1 as a marker in NPC patients. Finally, ALDH1A1 expression is high in spindle cells (cells that are prominently found in the invasive tumor front and the surrounding stroma) and may be responsible for the aggressive patterns and unfavorable prognosis in NPC patients.

General Methods for Examples

All air or moisture sensitive reactions were performed under positive pressure of nitrogen with oven-dried glassware. Chemical reagents and anhydrous solvents were obtained from commercial sources and used as-is. Preparative purification was performed on a Waters semi-preparative HPLC. The column used was a Phenomenex Luna C18 (5 micron, 30×75 mm) at a flow rate of 45 mL/min. The mobile phase consisted of acetonitrile and water (each containing 0.1% trifluoroacetic acid). A gradient of 10% to 50% acetonitrile over 8 minutes was used during the purification. Fraction collection was triggered by UV detection (220 nm). Analytical analysis for purity was determined by two different methods denoted as Final QC Methods 1 and 2. Method 1: Analysis was performed on an Agilent 1290 Infinity Series HPLC. UHPLC Long Gradient Equivalent 4% to 100% acetonitrile (0.05% trifluoroacetic acid) in water over 3 minutes run time of 4.5 minutes with a flow rate of 0.8 mL/min. A Phenomenex Luna C18 column (3 micron, 3×75 mm) was used at a temperature of 50° C. Method 2: analysis was performed on an Agilent 1260 with a 7 minute gradient of 4% to 100% acetonitrile (containing 0.025% trifluoroacetic acid) in water (containing 0.05% trifluoroacetic acid) over 8 minute run time at a flow rate of 1 mL/min. A Phenomenex Luna C18 column (3 micron, 3×75 mm) was used at a temperature of 50° C. Purity determination was performed using an Agilent Diode Array Detector for both Method 1 and Method 2. Mass determination was performed using an Agilent 6130 mass spectrometer with electrospray ionization in the positive mode. All of the analogs for assay have purity greater than 95% based on both analytical methods. ¹H spectra were recorded on Varian 400 (100) and 600 MHz spectrometers. High resolution mass spectrometry was recorded on Agilent 6210 Time-of-Flight LC/MS system.

Example 358 ALDH1A1 ENZYMATIC ASSAY (IN VITRO ASSAY)

3 μL of ALDH1A1 enzyme (final concentration 20 nM) or assay buffer (100 mM HEPES pH 7.5 with 0.01% Tween 20) were dispensed into a 1,536-well solid-bottom black plate (Greiner Bio One, Monroe, N.C.) followed by pin-tool transfer (23 nL) of candidate inhibitors (final concentration range 968 pM to 57.2 μM) and control (Bay 11-7085, final concentration range 1.31 nM to 2.86 μM). Samples were incubated (RT, protected from light) for 15 minutes followed by a 1 μL substrate addition of NAD⁺ and Propionaldehyde (final concentrations of 1 mM and 80 μM, respectively). Plates were centrifuged at 1,000 rpm for 15 seconds, then read in kinetic mode on a ViewLux High-throughput CCD imager (Perkin-Elmer) equipped with standard UV fluorescence optics (340 nm excitation, 450 nm emission) for 10 minutes. The change in fluorescence intensity over the 10-minute reaction period was normalized against no-inhibitor and no-enzyme controls and the resulting percent inhibition data were fitted for biological activity.

Example 359 MIA PACA2 CELL-BASED ASSAY (IN VITRO ASSAY) 1,536-Well High-Content Imaging ALDEFLUOR Assay

The ALDEFLUOR™ kit was purchased from STEMCELL Technologies (Vancouver, Canada; #01700). MIA PaCa-2 cells (5 μL; 1,000 cells/well) were dispensed into black, optical quality (cyclic olefin copolymer) clear bottom, medium binding TC treated 1,536-well plates (Aurora Microplates, Whitefish Mont.) using a Multidrop Combi dispenser (ThermoFisher) and incubated overnight (37° C., 5% CO₂, 85% RH). Media (RPMI 1640 (Life Technologies, Carlsbad, Calif.), supplemented with 2mM L-Glutamine (Life Technologies), 10% HyClone™ fetal bovine serum (FBS, GE Healthcare, Piscataway, N.J.) and 100 U/mL penicillin and 100 μg/mL streptomycin (Life Technologies)) was subsequently removed by centrifuging plates upside down using a plate adaptor to collect media. A solution of BAAA substrate (STEMCELL Technologies) and Hoechst 33342 (ThermoFisher, final concentrations of 500 nM and 0.5 nM, respectively) in ALDEFLUOR™ buffer (STEMCELL Technologies #01700) was dispensed onto cells using a Multidrop Combi followed by immediate transfer (23 nL) of compound or control solutions using a Wako Pin-tool (final percentage of DMSO in the cell plates was 0.5%). Unless otherwise noted, all compounds were assayed as 16-point dilutions spanning a final concentration range of 1.4 nM to 47.8 μM. The neutral and positive assay controls were DMSO and DEAB (4.6 μM), respectively. Cells were incubated for 30 minutes or the indicated amount of time at 37° C., 5% CO₂, 85% RH to allow the conversion of BAAA into BAA. Supernatant was subsequently removed by centrifugation as described above, then ALDEFLUOR™ buffer (3 μl) was dispensed by Multidrop Combi before imaging on an IN Cell 2200 (GE Healthcare).

The above assay was modified for an online robotic screening system. After cell plating and overnight incubation, 4 μL of media were removed using a 64-tip metal aspirator head on a Wako aspirator station, leaving 1 μL remaining in the well, followed by a 4 μL dispense of BAAA and Hoechst 33342 in ALDEFLUOR™ buffer, for a final concentration of 500 nM and 0.5 nM, respectively Immediately following the dispense, 23 nL of compound or control solutions were transferred using a Wako Pin-tool. Cells were incubated for 30 minutes at 37° C., 5% CO₂, 85% RH, followed by a 4 μL media removal using the Wako aspirator, and a subsequent 3 μL addition of ALDEFLUOR™ buffer. Plates were then immediately read on the IN Cell 2200 as described below.

Image Acquisition and Analysis

For images captured on the IN Cell 2200 widefield automated microscope, a 10×0.45 NA Plan Apo objective lens was used to capture the entire well of the 1,536-well plate using standard DAPI (390/18×, 432/48 m) and FITC (475/28×, 525/48 m) filter sets at 50 msec and 100 msec exposures, respectively. Images were subsequently analyzed using IN Cell Investigator v1.6.2 analysis software's canned Multi-Target Analysis algorithm (GE Healthcare). Hoechst stained nuclei were identified using top hat segmentation with a minimum area of 75 μm² and sensitivity of 93. BAA-retaining cells captured via FITC channel, were identified using multiscale top hat segmentation with a minimum area of 100 μm² and a sensitivity setting of 16. Several data measures were collected and the most robust measure for ALDH activity was found to be the integrated intensity (Intensity x Area) of the FITC channel. Data were plotted using GraphPad Prism software (GraphPad, San Diego, Calif.).
